For those curious SoCal folks looking for a mild tune and aren't truly looking to be dyno kings or trying to set/break records, it's so far been a good tune. The Weistec tune is a conservative tune with longevity and reliability in mind and is comparable to the Jb4 map1/2 that I was running. This was the goal I had in mind with my tune which is the reason I went ahead with them, being local also helped quite a bit. Simple set it and forget it.
AFRs are now within a good and safe range of 11-13 depending on where you are in the rpm band. I was running allover the place on the JB4(full disclosure, I wasn't running
fuel wires and I'm sure people will flame on that) from 10-15. They reduced the power loss on shift by increasing torque limits, which makes for smoother power delivery. The car is very smooth and feels less rough on acceleration and shifts (I didn't mind that much considering I came from a tuned G37 with a rough aggressive tranny and a V8 baby monster e92). MPG went up in normal driving and consistently seeing 20mpg of mixed driving including ~10 miles of Socal traffic mixed in. Haven't had the chance to do a long highway drive, but looking forward to seeing how that turns out.
I went from 362hp/426tq (jb4 map1) to 383hp/410tq (Weistec). I have junbl mids, thermal exhaust,
velossa tech, stock box with k&n drop ins. I am going back tomorrow to get some fine tuning done since I put my
Injen intakes back on and want to get some more increases to load limits in the mid rpm range. The tuning they advertised was done for AWD, so they have some things that I wanted changed for my RWD. I may also eventually stack my jb4 for a little more boost, but I'm happy for NOW. That changes over time, "ask any real racer" LOL.
All in all, I am satisfied for now with my Dad Mobile while I internally debate what my next project car will be for true go fast numbers (I sold my e92 M3 a little after I got the Stinger. Still a big regret, but $16k in cash was tough to turn down). An interesting thing I've learned throughout this process is the ability of tuners to tweak their dynos to reflect higher numbers - STD vs SAE, smoothing 5 vs 1-3, etc. I started taking a look at everyone's dyno charts and noticed the differences from tuner to tuner, not all charts are apples to apples. I guess you can get a bit higher numbers based on how you fiddle with various factors. I'm not endorsing one tuner vs. another, people can make their own decisions based on what they want out of their car. MY goal was accomplished and dealing with Weistec has been good.
